locality: Buenos Aires, Argentina. in my backyard.
date that i cought her: 29/12/2017
body length: 10mm
if you need any more information just ask for it.
Thank you very much .

If you enjoy my expertise and identifications, please do not put wild populations at risk of disease by releasing pet colonies. We are responsible to give our pets the best care we can manage for the rest of their lives.

Since this queen has two petiole nodes (waist segments), that would put her in the Myrmicinae subfamily (acorn ants, harvester ants, fire ants, etc.) Formica have one petiole node and belong to Formicinae (carpenter ants, rover ants, crazy ants.) Formica are also not present in South America, nor in most of the southern hemisphere.

I see, lol I guess I still have a lot to learn

Let us remember that even though ants are wonderful creatures, even more magnificent is their creator
